LINOTYZPE on SLUG-CASTING MACHINE.

To all whom it may concern Be it known that I, JOHN W. GRAHAM, a citizen of the United States, residing at Hinton, in the county of Summers and State of West Virginia, have invented certain new and useful Improvements in Linotype or Slug-Casting Machines, of which the following is a specification.

My invention relates to typographical machines, such as linotypes of the original construction, wherein circulating matrices are released from a magazine, in the order in which their characters are to appear in print, and then assembled in line together with expanding spacers, the composed line brought in contact with the face of a mold, the mold filled with molten metal, to form a line of type or slug against the matrices, which produce the type characters thereon, and the matrices thereafter returned to the magazines, from which they were originally drawn.

More particularly it relates to that class of machines, having a series of magazines, any one of which can be brought into operative position and locked therein and to that end I provide a basket or rack to house, in this instance, eight magazines, but I do not limit myself as to the number, and I further provide means by which the series can be lowered or raised by power mechanism, and such appliance is so arranged, that when the power raising or lowering device is put in motion, it first unlocks the magazines and throws the channel entrance, 'escapement channel and key rods, back out of the way of the magazines, and then moves the series of magazines up or down, as desired, and

particular stress is laid on the novel and ingenious arrangement of the mechanism, it being impossible to move the magazine until the channel entrance and escapement channel is thrown out of the way, and also that all the operations are brought about by turning the hand wheel. Turning the said hand wheel in the opposite direction causes the same series of operations, and reverses the direction of the travel of the basket and magazines, and further, that the roller on the lower end of the lock'operating rod, which roller rests in a'depression in the operating cam, is so arranged that when the cam is turned back to resting position, said roller acts as a stop for such cam 6 shows the mechanism for the Specification of Letters Patent.

and holds the cam from turning with the vibration of the machine when the machine is in operation. In the accompanying drawings I show my lnvention as an example, and in a preferred way and I wish it to be understood that I donot limit myself to any form or embodiment, except in so far as such form or embodiment is specified in the claims. It is apparent that many changes and variations will suggest themselves to those skilled in mechanical contrivances of this nature, and still not depart from the spirit or principle of this invention. I

In operating the machine, to raise or lower the magazines, the hand wheel or crank C on the cam. C, which in turn is on the shaft C is turned, this operation turns the cam C, which cam when turned a sufficient distance, causes the roller C on the lowerextremity of the-lockoperating rod (3", torise, and forces the wedge 0 between the rollers R,thu's forcing the two rods C apart one toward the front and the other toward the rear and releasesthe lock pins C from their socket holes Y. The front rod C is connected to the escapement channel and forces such channel outward and away from the magazines, such channel being conto be turned out and returned to position without interfering with the lock, and the said channel entrance is held in place by the spring F When the cam G is turned to a sufficient distance it operates the worm D on the shaft O and throws the friction wheel D on the front end of the shaft D against one or the other of the moving friction wheels D or D on the shaft D, which shaft is already on all machines of the class described and is in continuous motion when machine is in operation, such engagement of friction wheels causes the shaft D .to coine'into motion and this rotates the shaft B at the rear, by means of the intermeshed bevel gears D and D", the rear shaft B is fitted with the sprocket wheel K and connected to the frontal cross shaft B which is the sprocket chain K thus both cross shafts are brought into simultaneous motion, the two shafts B" are connected at their ends to the screws B, by bevel gears, thus the four screws 13* are brought into simultaneous motion, thus raising or lowering the basket. To operate the hand raising and lowering device, the hand wheel or crank C is turned to-unlock the magazine, the hand wheel K shown in Fig. 2 is then turned, this wheel'being directly on the frontal shaft B and the motion is transmitted to the four screws B as above stated. When the crank G is turned back to position the roller C drops into the depression in the cam C and the coil spring G throws the rod C downward thus releasing the rods C whichare thrown entrance and also the escapement channel and key rods back to operative position; also operating the lock pins C back into their socket holes Y, and such lock pins C pass through the piece A and into holes in the pieces B thus locking the magazine firmly in position. a
